Question 86 Explanation:

Given, 2/3 of the work completed in 64 days.
So, work completed in a day=2/(3*64) and 120 workers were working for 64 days
so, work done per day by a single worker= 2/(3*64*120)
So, in 124-64= in 60 days amount of work left 1/3
If x is the number of workers needed
(x*2*60)/(3*64*120)=1/3 so x=64 so the required answer 120-64=56
